Well, you have not actually created a COM server here. What you have
registered is an empty COM server that defines no methods. You haven't
actually used any methods from comtypes or comtypes.client at all.
You need to read the documentation for comtypes.server. You have to
create an IDL file (Interface Description Language) that defines the
methods you expect to expose. You compile that IDL to a type library
(TLB). Then, you use comtypes.client.GetModule to generate a wrapper
for that IDL. Then, your "testscript" module must derive from that
class, and implement the methods you declared.
comtypes creates an "early binding" COM server. Depending on the
languages you want to use, you might find it easier to create a "late
binding" server using Pythoncom, as described here:

No IDL is required with this method.
